Cable Plug Connector PCI-E 5.0 Power Cable 12VHPWR 12+4Pin

The 16‑pin PCIe 5.0 power cable (12+4, commonly referred to as 12VHPWR) is the new high‑current GPU power connector. The plug contains 12 power pins plus 4 signal/identification pins and is used to deliver power from ATX/ATX‑v3/Type‑4 compatible PSUs to modern graphics cards.

Key points: the compact 16‑pin plug uses high‑current contacts and appropriately sized conductors (vendors commonly use 16 AWG wiring) to support very high power delivery over a single cable. It carries the power lines and a sense signal for the GPU/PSU to negotiate power, simplifying connections for high‑end GPUs and enabling single‑cable delivery of several hundred watts when paired with a compatible PSU or adapter.
